Everyone has that dream about that toilet don't they? A friend of mine used to have this recurring toilet dream, especially when she was stressed. In it, she would be desperate for the toilet but could never actually find somewhere private to go. You know the ones. You walk into a beautifully clean public toilet, with row upon row of pristine, porcelain lavs and you can't believe your luck. But then you look closer and you see that none of the cubicles have any doors!

Or you sit down on the toilet, just about to relieve yourself when you notice the entire wall to your left is actually a window our on to a busy street. Everyone doing their Saturday morning shopping has a perfect view of you, in the middle of your ablutions. Nice.

I remember my toilet dream and I've only ever had the one, from when I was about six. I was an artist who was installing a toilet cubicle in the centre of a gallery. Just before the exhibition opened I realised I needed to go, so had to dash inside. Mid-flow all four walls fell down and I was exposed to a room full of people. I remember thinking when I'd woken up, that it was a bit odd. Until that point I really didn't have any knowledge of artists or what they did.
